For what's its worth, I had a very complicated June and July, and I got exactly what I was owed. That of course does not change the fact that none of us got August backpay.

From my record keeping:

June - Reconciled

July - Reconciled

August - Missing all backpay (base, rev, OG, UG)

September - Reconciled (except for September OG/UG as this is not contractually due until next month's EOM paycheck)

YMMV.
